RESILIENT WHEEL.

Specification of Letters Patentf Patented Sept. 27, 1921.

. Application filed September 17, 1920. Serial at. 410,974. -s

To all whom it may concern Be it known that I, JOSEPH Anno, citizen of the United States, residing at- Newhall, in the county of McDowell'and State of West Virginia,'hav.e invented certain new and useful: Improvements inv Resilient Wheels, of which the following is a specification.

provision of a'novel and improved type of resilient wheelof simple. and inexpensive construction.

More specifically speaking the invention has for an object to provide a resilient wheel arranged in a plurality of units orsections which may be readily replaced individually if Worn'or broken. V I

' For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to'the' following description and accompanying drawings, and to the appendedycl'aims in which the various novel features of the invention ter with the openings 23.

are more particularly set forth.

Figure 1 of the drawings is a face View 1 of an automobile wheel having-the 1nven-cr tion applied thereto.

Fig. 2 is an edge view thereof. r

Fig. 3 is an enlarged fragmentary section looking in the same direction as Fig. 1, this view being taken on the line 3-3 of Fig. 4.

Fig. 4: is a transverse section on the line 4-4 of Fig. 3. i I

In the drawings 10 indicatesfthehub of an automobile wheel and 11 the spokes radiating therefrom, and provided with diminished ends 12, these parts being of ordinary construction except that the spokes are comparatively short in proportion to the total diameter of the wheel, one feature of the invention having reference to the mounting of a novel type of felly upon the spokes.

In constructing the felly of my improved wheel I preferably form the same of a series of sections 13 which are secured together by means of pins or bolts 14 which pass through eyes 15 formed on the ends of the sections. These sections are placed individually upon the spokes 11 and are the wheel.

which receive the diminished ends 12 of the spokes and beingpreferably formed on their inner faces withenlarged recesses 16 which register with these openings.

vUpon this felly is mounted the resilient structure of the wheel which comprises a series of movable rim sections 18. of metal upon which are mounted the rubber tread members 19, the rim sections having side flanges 20 which engage. the sides of the tread member's.

Formed on the outer face of each of the rim "sections toward opposite ends thereof are a" pair of bosses 21 which receive the means whereby the rim sections are mounted on the felly. As here shown this means comprises a pair of bolts 22 for each sec tion whose threaded ends project outwardly and engage in suitable tapped bo-rings in the bosses 21. These bolts project through suitable openings 23 in the felly members which are enlarged to permit ofslight latbolts having heads 24 thereon located and guided in enlarged. sockets 25 in the inner faces ofthe felly members 13, which regis- Thesecsockets 25, it will be noted are flared in the plane of, the wheel asclearly shown in Fig. 3 while transversely of the wheel they presentparallel walls with. which the sides of the bolt heads 24 have a sliding fit. This construction allows for such angular or swinging movement in the plane of the rim as may occur as the different sections engage and disengage from the surface of the road in rotation, while holding the sections against movement transversely to In order to further strengthen the rim against such transverse movement I may provide a series of rigid radial flanges 26 on the felly members which project on opposite sides of the rim sections.

Encircling'the bolts 22 are coiled expansion springs 27 which bear between the elly members 13 and rim sections 18, the inner faces'of the latter being preferably recessed as at 28 to receive the outer ends of the springs.

As shown in the drawings the tread and rim sections of the wheel are preferably spaced circumferentially apart a short distance to allowof relative movement the rim sections 20 being similarly spaced while each .80. eral movement of the bolts, therein, the

alternate tread section is preferably formed at the ends with projecting flanges 29 which are accommodated in angular recesses 30 on the adjacent sections. The tread sections 19 are also formed with suitable recesses 31 to receive the outer ends ofthe bolts.

In constructing the tread surfaces of these tread sections 1 preferably provide them V with frictional devices which are varied in of simple construction and the various parts thereof may be readily renewed individually when desired, while the resiliency may be varied as 'desired' by. adjusting the bolts 22 inthe bosses 21.

Having thus described my invention what.

I claim as new and desire to protect byLetters Patent of the United States is as fol- I lows. V V

r 1. In a vehicle wheel, a felly, a series of "metallic rim sections resiliently mounted'on said felly and having their adjacent ends spaced a short distance apart'circumferentially of the wheel, separate resilient tread sections fixed on said rim sections, certain ones of said tread sections having projections at their ends overlapping the ends of adjacent sections.

2. In a vehicle wheel, afelly, a series of metallic rim sections-resiliently mounted on said felly and having their adjacent ends spaced a short distance apart circumferen-' tially of the wheel, separate resilient tread sections fixed on said rim sections, certa n ones of said tread sections having their surface portions extended to overlap the ends of adjacent tread sections, the main bodies 'movement'in the'plane-of the wheel. U 5. Ina vehiclewheel, a felly, a seriesof' bolts carried thereby to have free radial movement and projecting:therebeyond, a Y series of rim sections having thesaid bolts of said tread sections being spaced eircum ferentially from onefanother in eorrespond ence to the spacing of said rim sections.

3. Ina vehicle wheel, a felly, a series of metallic rim sections resiliently mounted on said felly and having their adjacent ends spaced a short distance apart circumferen tially of the wheel, separate resilient tread sections fixed on said rim sections, the alteriiate tread sections having respectively projections and recesses at their ends,- the said pro ections being accommodated inthe said recesses.

4. In a'vehiele wheel, afelly, a series'of v bolts carried thereby toihavei free radial movement and projecting therebeyond, a series of r m sections hav ng the said bolts screwed in pairs thereinto and coiled eX- pansion springs surrounding said bolts and. interposed between said fel'ly and said rim sections, heads uponsaid bolts, and means" upon sa'id felly 'engagingsaid heads to prevent; angular movement of the bolts trans versely of the wheel while permittingvsuch screwed in pairs thereinto and coiled expansion springs surrounding said boltsand in- 'terposedb'etween said fellyandsaid rim sections, heads upon said bolts, and means upon said 'felly engaging'said heads to prevent angular movement of the bolts transversely of the wheel while permitting such movement in the plane of the wheel, said means comprising sockets in said felly having the walls thereof flared in the plane of;

the wheel-butparallel transversely thereto.

In testimony whereof I signature.
